SaidY crank ,arm 37 is mountedV on the shaft of the rotary valve 1,3 before mentioned; rlhe connection between the rod 36 and tl elever arm 35is'in t ie l form of a bearing block 38 Whi ch isnivotalli connected to the outer end portion of the `lever Y arm 35. The rsaid bearing block 33 is slidably positioned in the-elongatedslot 39 o f the outer endportion 36 of the connecting rod36 to permit lost play and to rock the valve 13 with quick positive movement When the `arm 35 is near the end of each oscillation.

Said tube connections 53'and 54 are also provided With check valves 55 for preventing the return ofjthevvater to the source ofsupply or from the valve casing13 to the pump 16. Y

The rock valve 13 is of segmental form and its circumferential length is suticient to cover the upper inlet and the lower outlet openings or ports ,56 and'57 of the-rock valve casing, so that on the outer or suction stroke of the feed cylinder piston 22 the rock valve 13 Will j close theoutlet opening 57 and draw the corn or other material into the feed'v cylinder 14. During the inner or feed stroleofthe piston 22^the rock valve 13 uncovers theoutlet open ing 57 and covers the inlet opening 56 With the' result that the corn orother material `is forced bythe piston from'. the cylinder v through the port ork opening. 57 and into the.

drumll for sterilization'or cooking. A'tube 58, connected tothe upper portion ofthe end of'the'drum to Which the steam pipe 47 is connected, provides for tliecontinuous discharge of the corn or other material from said drum v by the pressure of the feed piston,

F orcfonvenience in gaining access `to the interior ofthe drum vfor cleaning purposes, the head 59 of the drum is removable and is held inl clamped position thereon by threaded swing rodsk60 and thumb nuts 61. j

From the foregoing description it Will be seen that the proportional heater vis of very simple construction and is provided with pumps having pistons, the strokes of which may be adjusted by means of the bearing arms to control the proportionate amount of brine andjvater to bemixed with the corn or other material in passing through the machine. It Will valso be seen that the corn is subjected to an even cook due tothe rotary steam jets being directed into all portions of the corn .passing kthrough the drum, and that the feed tive movements.
